44602b0868 rename libguile to libguile-@EFFECTIVE_VERSION@, currently libguile-2.0
* libguile/Makefile.am (lib_LTLIBRARIES): Instead of just "libguile.la",
  make "libguile-@EFFECTIVE_VERSION@.la". This allows multiple versions
  of Guile to be installed at once. See
  http://www106.pair.com/rhp/parallel.html for a rationale.

  (libguile_@GUILE_EFFECTIVE_VERSION@_la_CFLAGS):
  (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
  (EXTRA_libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
  (libguile_@GUILE_EFFECTIVE_VERSION@_la_DEPENDENCIES):
  (libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD):
  (libguile_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS): Fixup automake vars
  to include the effective version.
  (guile_LDADD): Fix up the spelling of libguile.

* libguile/bytevectors.c (scm_bootstrap_bytevectors):
* libguile/foreign.c (scm_register_foreign):
* libguile/i18n.c (scm_bootstrap_i18n):
* libguile/instructions.c (scm_bootstrap_instructions):
* libguile/objcodes.c (scm_bootstrap_objcodes):
* libguile/programs.c (scm_bootstrap_programs):
* libguile/vm.c (scm_bootstrap_vm): Register extensions using e.g.
  "libguile-2.0" as the libname -- i.e., including the effective version
  in the libname.

* module/rnrs/bytevector.scm:

* module/system/foreign.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: When doing a load-extension for something in
  Guile, use the effective version also.

* meta/guile-2.0-uninstalled.pc.in (Libs):
* meta/guile-2.0.pc.in (Libs): Use -lguile-@EFFECTIVE_VERSION@. This
  change should mean that code built against Guile should not be
  affected by the libguile rename.

* guile-readline/Makefile.am (libguilereadline_v_@LIBGUILEREADLINE_MAJOR@_la_LIBADD):
* srfi/Makefile.am

42ee0d00ba (debug) at the repl invokes the vm debugger
* module/ice-9/boot-9.scm (top-repl): Map (debug) at the repl to (system
  vm debug).

* module/system/vm/debug.scm (run-debugger, debugger-repl): Don't take
  the index as an arg, for now anyway.
  (debug): New wrapper.

06dcb9dfb6 narrowing stacks to prompts; backtrace shows frames from start-stack
* libguile/stacks.c (scm_sys_stacks): New global variable, moved here
  from boot-9.scm.
  (scm_init_stacks): Define scm_sys_stacks to %stacks.
  (stack_depth): Remove narrowing by frame pointer.
  (find_prompt): New helper.
  (narrow_stack): Clean up a bit, and allow narrowing by prompt tag.
  (scm_make_stack): Update docs, and use scm_stack_id to get the stack
  id.
  (scm_stack_id): The current stack id may be fetched as the cdar of
  %stacks.
  (stack_id_with_fp): Remove helper.

* module/ice-9/boot-9.scm (%start-stack): Fix indentation.
  (%stacks): Remove definition, it's in stacks.c now.
  (default-pre-unwind-handler): Narrow by another frame.
  (save-stack): Remove special handling for certain stack ids, as it is
  often possible that the function isn't on the stack -- in the
  interpreter, or after a tail call. Better to narrow by prompt ids.

* module/system/vm/debug.scm (print-frames): Change to operate on a
  vector of frames.
  (run-debugger): Change to receive a vector of frames. The debugger
  also has the full stack, so it can re-narrow (or widen) to get the
  whole stack, if the user wants.
  (stack->vector): New helper.
  (debug-pre-unwind-handler): Narrow by more frames, and to the most
  recent start-stack invocation. Adapt to run-debugger change.

7ea3e4ff28 vm-trace prints return values
* module/system/vm/trace.scm (vm-trace): Add a #:width argument. Print
  return values, as Chez Scheme does.

7e9f96021a vm-trace only traces execution of its thunk
* module/system/vm/trace.scm (vm-trace): Change to just export the one
  procedure, vm-trace. This way it's threadsafe and more robust. Also
  refactor to not print any of Guile's internal bits. Hopefully Neil
  will be happier :)

* module/system/repl/command.scm (option): Adapt to removal of
  vm-trace-on! and vm-trace-off!, as those are unlikely to DTRT.

8470b3f45b fix texinfo reflection for procedures
* module/system/vm/program.scm (program-arguments-alist): Rename from
  program-arguments, a name shadowed by features.c
  (arglist->arguments-alist, arity->arguments-alist)
  (arguments-alist->lambda-list, program-lambda-list, write-program):
  Adapt callers.

* module/system/vm/frame.scm (frame-lookup-binding): Return #f if the
  binding is not found, not an error.
  (frame-binding-set!, frame-binding-ref): Adapt to error appropriately.
  (frame-arguments): Dispatch to frame-call-representation.
  (frame-call-representation): Refactor a bit.

* module/ice-9/session.scm (procedure-arguments): Adapt to
  program-arguments name change.

* module/texinfo/reflection.scm (get-proc-args): Refactor to actually
  work with VM procedures.

e106eca674 inspector integration in debugger
* module/system/vm/debug.scm: Integrate with the inspector. Add a
  "procedure" command.

136b5494d1 programs print as #<procedure ...>
* module/system/vm/program.scm (write-program): Print as #<procedure

ecdf15573b show args to subr calls in backtraces
* module/system/vm/frame.scm (frame-arguments): For subrs, we don't get
  names in the lambda-list, we get #f instead. But still, parse out the
  args in that case, assuming they are on the stack in that order.

913ddf0574 slight tweak to stack narrowing in the debugger
* module/system/vm/debug.scm: Really narrow two frames and not by
  function, so it works in the evaluator.
2010-01-09 21:53:04 +01:00
Andy Wingo
37e9bc8ae4 Narrow one more frame in debug.scm:debug-pre-unwind-handler
* module/system/vm/debug.scm (debug-pre-unwind-handler): Narrow two
  frames instead of stack-reffing past one. The second frame is
  necessary, now that make-stack itself is on the stack.
2010-01-09 20:40:36 +01:00
Andy Wingo
391d29029d print the error more nicely when we enter the debugger
* module/system/vm/debug.scm (debug-pre-unwind-handler): Nicer printing
  of the error.

8217c9251a make backtraces prettier
* module/system/vm/debug.scm (print-frames): Clean up a bit, reverting
  part of the previous change. (The problem was that in the else branch
  of the conditional, it didn't consume an arg.)

  In the future I would like to preserve the clean look of the
  backtraces. It's easier to read that way.

6f16379e9a allocate free variables inline to closures
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.

* libguile/programs.h (SCM_PROGRAM_FREE_VARIABLES)
  (SCM_PROGRAM_FREE_VARIABLE_REF, SCM_PROGRAM_FREE_VARIABLE_SET)
  (SCM_PROGRAM_NUM_FREE_VARIABLES):
* libguile/programs.c (scm_make_program, scm_program_num_free_variables)
  (scm_program_free_variable_ref, scm_program_free_variable_set_x):
  Allocate free variables inline with programs, instead of being in a
  vect. Should improve locality, and require fewer local variables in
  the VM.

* libguile/vm-engine.c (vm_engine): Remove free_vars and free_vars_count
  variables.

* libguile/vm-engine.h (CACHE_PROGRAM): No need to muck with free_vars
  and free_vars_count.
  (CHECK_FREE_VARIABLE): Update for inline free vars.

* libguile/vm-i-system.c (FREE_VARIABLE_REF): Update for inline free
  vars.
  (make-closure, fix-closure): Take the closure vals as separate stack
  args, and copy or fix them inline into the appropriate closure.

* module/language/objcode/spec.scm (program-free-variables): Define a
  local version of this removed function.

* module/language/tree-il/compile-glil.scm (flatten): Adjust to not make
  a vector when making closures.

* module/system/vm/program.scm: Export program-num-free-variables,
  program-free-variable-ref, program-free-variable-set!, and remove
  program-free-variables.

* test-suite/tests/tree-il.test ("lambda"): Update to not make vectors
  when making closures.

a589525d4e Fix frame printing in the debugger.
* module/system/vm/debug.scm (location-string): New procedure.
  (print-frames): Use it.  This fixes cases where LINE is #f and makes a
  distinction between FILE = stdin and FILE is unknown.

6f3b0cc29e tc7 tags for vm-related data
* libguile/tags.h (scm_tc7_frame, scm_tc7_objcode, scm_tc7_vm)
  (scm_tc7_vm_cont): Take more tc7s for VM-related data structures.

* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of, create_standard_classes):
* libguile/print.c (iprin1): Add cases for the new tc7s.

* libguile/frames.c:
* libguile/frames.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/vm.c:
* libguile/vm.h: Desmobify.

* libguile/vm.c (scm_vm_apply): Export to Scheme, because VM objects are
  no longer applicable.

* module/system/repl/command.scm (profile):
* module/system/vm/trace.scm (vm-trace):
* module/system/vm/vm.scm (vm-load): Call vm-apply to run a program in a
  VM instead of treating the VM as applicable.

441891f376 cleanups to debugger
* module/system/vm/debug.scm (debugger-repl): Remove the `bindings'
  command, it is superseded by `locals'.
  Update the TODO.
  (debug-pre-unwind-handler): Remove scary "beta" warning. Already being
  able to bt #:width 1000 #:full? #t is quite useful...

0c2a05c321 debugger's backtrace implemented in scheme
* module/system/vm/debug.scm (print-locals): Factor out to a function.
  (collect-frames, print-frames): Implement the guts of `backtrace' in
  Scheme.
  (debugger-repl): Add #:width and #:full? options to `backtrace'.
  Backtrace uses the backtrace code implemented in scheme.

2d8c757cf1 integers at debugger select frames

  N".

1c5e812258 clean up (system vm frames), add locals command to debugger
* libguile/frames.c (scm_init_frames): No need to bootstrap the VM here,
  it should be already bootstrapped by init.c.
  (scm_bootstrap_frames): No need to register an extension, as
  scm_init_frames is called by init.c.

* module/system/vm/frame.scm: Don't load the scm_init_frames extension,
  as the primitives from frames.c are loaded by Guile's init.
  (frame-bindings): Change to return bindings, as can be accessed by the
  binding: accessors from program.scm.
  (frame-lookup-binding): Revive and make this one work with current
  code.
  (frame-binding-set!):
  (frame-binding-ref): Use the new frame-lookup-binding. Perhaps these
  should handle boxing and unboxing, though.
  (frame-source): New accessor, returns a source object.
  (frame-call-representation): Change to return a full list, as
  truncated-print can truncate for us.
  (frame-environment, frame-object-binding, frame-object-name): Update
  not to take an address, as the address is part of the frame.
  (frame-variable-exists?, frame-variable-ref, frame-variable-set!)
  (frame-local-variables, frame-program-name, print-frame)
  (print-frame-chain-as-backtrace, frame-file, frame-line-number)
  (make-frame-chain, bootstrap-frame?, frame-number, frame-address):
  Remove these outdated functions.

* module/system/vm/debug.scm (debugger-repl): Use
  frame-call-representation, and ~@y.
  (locals): New command, prints local variables in a frame.

1ad7fef524 implement a silly debugger
* module/system/vm/debug.scm: Implement the skeleton of a debugger. Not
  very useful yet.

* module/system/repl/repl.scm (call-with-backtrace): Have the pre-unwind
  hook drop the user into the debugger. Hopefully we can have something
  better within a couple weeks.

Andy Wingo
7656f19446 rework vm tracing
* libguile/vm-engine.c (VM_NAME): Engines take the VM itself (not the
  vp), so they can pass the VM to hooks. No more hook args, we dispatch
  without them.

* libguile/vm-engine.h (RUN_HOOK): Dispatch the hook if the trace level
  is positive (instead of if the hook is there). Don't cache registers
  on return from the dispatch.

* libguile/vm.h:
* libguile/vm.c (vm_dispatch_hook): Don't bother with a dynwind; instead
  decrement the trace level when going into a hook, and if we have a
  nonlocal exit, the trace level never gets incremented again. Worse is
  better.
  (make_vm, scm_vm_trace_level, scm_set_vm_trace_level_x): New concept,
  trace level. If positive, we run the hooks, otherwise we don't. Should
  work. Removed scm_vm_trace_frame, I don't think that was the right way
  to do it.

* module/system/vm/vm.scm: Replace vm-trace-frame with vm-trace-level
  and set-vm-trace-level!; the hooks actually get the frame as an
  argument now.

6c20a0b34b vm no longer measures bogoclock or times, relies on os for that
* libguile/vm.h (struct scm_vm): Remove "time" and "clock" members. The
  time was bogusly measured, and the "clock" measured instructions
  retired, which is not a very useful measurement, and it was causing
  lots of memory accesses. Not that I have done a proper profile,
  though...
  (scm_vm_stats): Remove this procedure, which provided access to "time"
  and "clock".

* libguile/vm.c:
* libguile/vm-engine.h:
* libguile/vm-engine.c:
* libguile/vm-i-system.c: Adapt to scm_vm changes and scm_vm_stats
  removal.

* module/system/repl/command.scm:
* module/system/vm/vm.scm: Adapt to vm-stats removal by removing
  vm-stats from <repl>.

08d7492cf0 add gbt macro to gdbinit, and fix a bug in program-arity
* gdbinit: Add gbt macro, to make a Guile backtrace whenever you want.

  the first arity.

aa3f69519f replace frame implementation with VM frames
* libguile/stacks.h: Rework so that a stack doesn't copy information out
  of VM frames, it just holds onto a VM frame, along with the stack id
  and length. VM frames are now the only representation of frames in
  Guile.
  (scm_t_info_frame, SCM_FRAME_N_SLOTS, SCM_FRAME_REF, SCM_FRAME_NUMBER)
  (SCM_FRAME_FLAGS, SCM_FRAME_SOURCE, SCM_FRAME_PROC, SCM_FRAME_ARGS)
  (SCM_FRAME_PREV, SCM_FRAME_NEXT)
  (SCM_FRAMEF_VOID, SCM_FRAMEF_REAL, SCM_FRAMEF_PROC)
  (SCM_FRAMEF_EVAL_ARGS, SCM_FRAMEF_OVERFLOW)
  (SCM_FRAME_VOID_P, SCM_FRAME_REAL_P, SCM_FRAME_PROC_P)
  (SCM_FRAME_EVAL_ARGS_P, SCM_FRAME_OVERFLOW_P): Remove these macros
  corresponding to the old frame implementation.
  (scm_frame_p scm_frame_source, scm_frame_procedure)
  (scm_frame_arguments): These definitions are now in frames.h.
  (scm_last_stack_frame): Remove declaration of previously-removed
  constructor. Probably should re-instate it though.
  (scm_frame_number, scm_frame_previous, scm_frame_next)
  (scm_frame_real_p, scm_frame_procedure_p, scm_frame_evaluating_args_p)
  (scm_frame_overflow_p) : Remove these procedures corresponding to the
  old stack implementation.

* libguile/stacks.c: Update for new frames implementation.

* libguile/frames.h:
* libguile/frames.c: Rename functions operating on VM frames to have a
  scm_frame prefix, not scm_vm_frame -- because they really are the only
  frames we have. Rename corresponding Scheme functions too, from
  vm-frame-foo to frame-foo.

* libguile/deprecated.h: Remove scm_stack and scm_info_frame data types.

* libguile/vm.c (vm_dispatch_hook): Adapt to scm_c_make_frame name
  change.

* module/system/vm/frame.scm: No need to export functions provided
  frames.c now, as we load those procedures into the default environment
  now. Rename functions, and remove a couple of outdated, unused
  functions. The bottom half of this file is still bitrotten, though.

* libguile/backtrace.c: Rework to operate on the new frame
  representation. Also fix a bug displaying file names for compiled
  procedures.

* libguile/init.c: Load the VM much earlier, just because we can. Also
  it allows us to have frames.[ch] loaded in time for stacks to be
  initialized, so that scm_frame_arguments can do the right thing.

f916cbc4b1 update procedure docs for programs, lambda*, case-lambda
* module/system/vm/program.scm: Export the arity things again, and
  program-arity. Why not.

* doc/ref/api-procedures.texi (Compiled Procedures): Update for current
  API.
  (Optional Arguments): Update to assume lambda* and define* are always
  available, and (ice-9 optargs) is now the ghetto.
  (Case-lambda): Now here, moved from SRFI-16 docs. Also docs
  case-lambda*.

* doc/ref/srfi-modules.texi: Point to core case-lambda docs.

df435c8307 arities can have noncontiguous starts and ends
* module/language/glil/compile-assembly.scm (open-arity, close-arity)
  (begin-arity, glil->assembly): Refactor so that arities can have
  noncontiguous starts and ends. So within a prelude there is no arity
  -- only before (the previous arity) or after (the new arity).

* module/system/vm/program.scm (arity:end): Add this private accessor.
  Arities are expected to be in the new format. While not a change in
  objcode format, it is an incompatible change, so I'll bump the objcode
  cookie.
  (program-arity): Check that the ip is within both bounds of the arity.

* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.

* libguile/programs.c (scm_i_program_arity): Update for new arity format.

* module/system/vm/frame.scm (vm-frame-arguments): Avoid throwing an
  error in this function, which is called from the backtrace code.

6c6a44390b runtime and debugging support for callee-parsed procedure args
* libguile/objcodes.h: Bump for metadata format change.

* libguile/frames.h: Rework so we don't frob the program's nargs, nlocs,
  etc at runtime. Instead we don't really know what's a local var, an
  argument, or an intermediate value. It's a little unfortunate, but
  this will allow for case-lambda, and eventually for good polymorphic
  generic dispatch; and the nlocs etc can be heuristically
  reconstructed. Such a reconstruction would be better done at the
  Scheme level, though.
  (SCM_FRAME_STACK_ADDRESS): New macro, the pointer to the base of the
  stack elements (not counting the program).
  (SCM_FRAME_UPPER_ADDRESS): Repurpose to be the address of the last
  element in the bookkeeping part of the stack -- i.e. to point to the
  return address.

* libguile/vm-engine.h:
* libguile/vm-i-system.c: Adapt to removal of stack_base. Though we
  still detect stack-smashing underflow, we don't do so as precisely as
  we did before, because now we only detect overwriting of the frame
  metadata.

* libguile/vm-engine.c (vm_engine): Remove the stack_base variable. It
  is unnecessary, and difficult to keep track of in the face of
  case-lambda. Also fix miscommented "ra" and "mvra" pushes. Push the
  vp->ip as the first ra...
* libguile/vm-i-system.c (halt): ...because here we can restore the
  vp->ip instead of setting ip to 0. Allows us to introspect ips all
  down the stack, including in recursive VM invocations.

* libguile/frames.h:
* libguile/frames.c (scm_vm_frame_stack): Removed, because it's getting
  more difficult to tell what's an argument and what's a temporary stack
  element.
  (scm_vm_frame_num_locals): New accessor.
  (scm_vm_frame_instruction_pointer): New accessor.
  (scm_vm_frame_arguments): Defer to an implementation in Scheme.
  (scm_vm_frame_num_locals scm_vm_frame_local_ref)
  (scm_vm_frame_local_set_x): Since we can get not-yet-active frames on
  the stack now, with our current calling convention, we have to add a
  heuristic here to jump over those frames -- because frames have
  pointers in them, not Scheme values.

* libguile/programs.h:
* libguile/programs.c (scm_program_arity): Remove, in favor of..
  (scm_program_arities): ...this, which a list of arities, in a new
  format, occupying a slot in the metadata.

* module/language/assembly/decompile-bytecode.scm (decode-load-program):
  Fix mv-call decompilation.

* module/system/vm/frame.scm (vm-frame-bindings, vm-frame-binding-ref)
  (vm-frame-binding-set!): New functions, to access bindings by name in
  a frame.
  (vm-frame-arguments): Function now implemented in Scheme. Commented
  fairly extensively.

* module/system/vm/program.scm (program-bindings-by-index)
  (program-bindings-for-ip): New accessors, parsing the program bindings
  metadata into something more useful.
  (program-arities, program-arguments): In a case-lambda world, we have
  to assume that programs can have multiple arities. But it's tough to
  detect this algorithmically; instead we're going to require that the
  program metadata include information about the arities, and the parts
  of the program that that metadata applies to.
  (program-lambda-list): New accessor.
  (write-program): Show multiple arities.

* module/language/glil/compile-assembly.scm (glil->assembly): Add
  "arities" to the state of the compiler, and add arities entries as
  appropriate.

  "unused". In the future we can use it for nlocs, I think.
  (SCM_OBJCODE_NEXTS): removed.

* libguile/programs.h:
* libguile/programs.c (scm_make_program): Expect the third argument to
  be a vector of free variables, not a list of free variables.

028e3d0666 propagate much more source info through compilation
* module/language/ghil/compile-glil.scm (codegen): Record source location
  for offset 0 into a lambda, if we can.

* module/language/scheme/compile-ghil.scm (translate-1)
  (define-scheme-translator): In the retrans procedures, propagate the
  location information from the enclosing expression if the subexpression
  has no location information. Gives source information to many more
  expressions.
  (location): Just propagate the source properties as they are, the
  glil->assembly compiler will interpret them.

* module/language/glil.scm (<glil>): Change glil-source to take "props"
  and not "loc", as it's the source properties that we're interested in.

* module/language/glil/compile-assembly.scm (limn-sources): New function,
  takes a list of addr-source property pairs and "compresses" them for
  serialization to disk.
  (glil->assembly): Limn the sources before writing them to disk. Avoid
  non-tail recursion when determining total byte length of code.

* module/system/vm/program.scm (source:file, source:line, source:column):
  Update for new source representation.
  (program-source): Export.
  (write-program): Nicer pretty-printing of anonymous procedures.

* libguile/backtrace.c (display_backtrace_get_file_line): Update for the
  new VM source representation.

* libguile/programs.h:
* libguile/programs.c (scm_program_sources): Update for the new
  serialized source representation, where the filename is not in the
  stream unless it changes.
  (scm_program_source): New exported function, looks up the source for a
  given ip offset.
  (scm_c_program_source): Update to return the last source information
  that was <= the given IP, because we only serialize source info when it
  changes.

* libguile/objcodes.c (make_objcode_by_mmap, scm_c_make_objcode_slice):

  (scm_objcode_meta): New procedure, for getting at the meta-info of an
  objcode.
  (scm_objcode_to_bytecode):
  (scm_write_objcode): Write bytecode with the metadata too.

* module/system/vm/objcode.scm: Export object-meta.

* module/language/assembly/disassemble.scm (disassemble-load-program):

* libguile/objcodes.h:

* module/system/vm/objcode.scm: Rename objcode->u8vector to
  objcode->bytecode.

* module/system/vm/frame.scm:

53e28ed9b2 static opcodes; refactor program/objcode division; use new assembly pipeline
* gdbinit: Untested attempts to get the stack fondling macros to deal
  with the new program representation.

* libguile/frames.c (scm_vm_frame_arguments, scm_vm_frame_source)
  (scm_vm_frame_local_ref, scm_vm_frame_local_set_x): SCM_PROGRAM_DATA is
  a struct scm_objcode*.

* libguile/instructions.h:
* libguile/instructions.c: Hide the instruction table and the struct
  scm_instruction structure; all access to instructions now goes through
  procedures. This is because instructions are no longer in a packed
  array indexed by opcode. Also, declare a mask that all instructions
  should fit in.

* libguile/objcodes.h:
* libguile/objcodes.c: Rewrite so that object code directly maps its
  arity and length from its bytecode. This makes it unnecessary to keep
  this information in programs, allowing programs to be simple conses
  between the code (objcodes) and data (the object table and the closure
  variables).

* libguile/programs.c (scm_make_program): Rework so that make-program
  takes objcode, an object table, and externals as arguments. It's much
  clearer this way, and we avoid malloc().

* libguile/stacks.c (is_vm_bootstrap_frame): Update for program/objcode
  changes.

* libguile/vm-engine.c (vm_run): Initialize the jump table on the first
  run, with the opcodes declared in the instruction sources, and with bad
  instructions raising an error instead of wandering off into the
  Unknown.

* libguile/vm-engine.h (FETCH_LENGTH): Always represent lengths as 3
  bytes. The old code was too error-prone.
  (NEXT_JUMP): Mask the instruction with SCM_VM_INSTRUCTION_MASK.
  (NEW_FRAME): Update for program/objcode changes.

* libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_INSTRUCTION)
  (VM_DEFINE_LOADER): Update so that we explicitly specify opcodes, so
  that we have a stable bytecode API.

* libguile/vm-i-loader.c: Update license to LGPLv2+. Explicitly declare
  opcodes.
  (load-integer): Use an int instead of a long as the accumulator; still
  need to revisit this code at some point, I think.
  (load-program): Simplify, thankfully!! Just creates the objcode slice
  and rolls with it.

* libguile/vm-i-scheme.c: Number the opcodes explicitly.

* libguile/vm-i-system.c: Update license to LGPLv2+. Explicitly declare
  opcodes.
  (make-closure): Update for new program API.

* libguile/vm.c (vm_make_boot_program): Update for new program/objcode
  API. Still a bit ugly.
  (scm_load_compiled_with_vm): Update for new program/objcode API.

* module/language/assembly.scm (byte-length): Fix byte-length calculation
  for loaders, and load-program.
  (code-pack, code-unpack): Start to move things from (system vm conv)
  here.
  (object->code, code->object): More things from conv.scm.

* module/language/glil.scm (<glil-program>): Add a new field,
  closure-level.
  (make-glil-program, compute-closure-level): Calculate the "closure
  level" when making a glil program. This is the maximum depth of
  external binding refs in this closure.
  (unparse-glil): Fix label serialization.

* module/language/glil/compile-assembly.scm (make-meta): Prepend #f for
  the meta's object table, though maybe in the future we can avoid
  creating assembly in the first place.
  (assoc-ref-or-acons, object-index-and-alist): GRRR! Caught again by the
  different sets of arguments to assoc and assoc-ref!
  (glil->assembly): Attempt to make the <glil-program> case more
  readable, and fix the bugs. Sorry I don't know how to comment this
  change any more than this.
  (glil->assembly): For <glil-module> serialize the whole key, not just
  the name.
  (dump-object): subprogram-code is already a list. Serialize integers as
  strings, not u8vectors. Fix the order of lists and vectors.

* module/language/glil/spec.scm (glil): Switch orders, so we prefer glil
  -> assembly -> objcode. Actually glil->objcode doesn't work any more,
  needs to be removed I think.

* module/language/objcode/spec.scm (objcode->value):
  s/objcode->program/make-program/.

* module/language/scheme/inline.scm: Add acons inline.

* module/system/vm/conv.scm (make-byte-decoder): Skip the first 8 bytes,
  they are header. Handle subprograms properly. Still needs help though.
  (decode-length): Lengths are always 3 bytes now.

* module/system/vm/disasm.scm: Superficial changes to keep things
  working. I'd like to fix this better in the future.

* module/system/vm/frame.scm (bootstrap-frame?): Fixes for
  program-bytecode.

* module/system/vm/program.scm: Export make-program. It's program-objcode
  now, no more program-bytecode.

* module/system/vm/vm.scm (vm-load): Use make-program.

* test-suite/tests/asm-to-bytecode.test: New test, very minimal.

* module/system/vm/objcode.scm: Export word-size, byte-order, and
  write-objcode.
